A practical handbook for collectors that surveys the development, production, and varieties of early American pressed flint glass made in New England factories. It combines a history of local glassmakers and works with technical explanations of materials, molds, pressing methods, and the distinctions between early hand-blown and later pressed commercial wares. The author catalogs representative forms such as cup plates, salts, candlesticks, lamps, and flatware, describes colors, molds, and identifying marks, and cautions against later mass-produced imitations. Numbered illustrations and a collector’s data section support identification and recordkeeping for the serious student of early American glass.
